     Such guarantee seal has a unique shape that fits exactly with the cavities of the meters and it gets in by pressure, therefore if the seal is located outside of such cavity its external manipulation is evident, furthermore, it has a lid, a base, a verification system by continuity and tag or RFID tag to ensure the integrity of such seal.

This invention is related to a non-reusable disposable guarantee sealfor non-opening electrical energy consumption meters with mechanicalclosure type padlock; for sealing or closing some container, box, door,cabinet, meter, valve, pump, bag, carrier bag, water tank, etc., meanlyused for the electricity meters commonly used in countries of NorthAmerica, Central and South America; intended for protecting andcontrolling the electricity theft, guarantying its immobility.

Such guarantee seal has a unique shape that fits exactly with thecavities of the meters and it gets in by pressure. If the seal islocated outside of such cavity its external manipulation is evident,furthermore, it has a lid, a base, a verification system for continuityand RFID tag or tag to ensure the integrity of such seal.

BACKGROUND OF THE INVENTION

In the art there are several seals or security seals for protection ofproducts, however, such seals and/or security seals used especially inelectricity meters in Mexico, use a pawl system linked to a femalemember in its side walls and a male member with arrow-shaped guideshoes, half arrow or gear. These seals have disadvantages because theycan be violated not obviously or not easily visible through smallperforations to the sides allowing to push the guide shoes, resultingeasily releasable, besides not being suitable for joints where it isintended to maintain the inviolability and needs to be clearly evidencedthe existence of handling.

Besides, the structures of the conventional seals use corrosivematerials, such is the case with the lead seals which commonly use atwisted wire, for which the employment is not easy or practical sincethey need tools for closing as pliers for lead seals.

The design of conventional seals is usually colored, however, hardlythey evince his fracture or manipulation.

In the prior art we have the patent document U.S. Pat. No. 4,263,697which refers to one-piece security seal in one piece which is cheap andsimple for manufacturing by mass production methods, however, it hasdrawbacks for leaving the clamp mechanism exposed to possiblemanipulation, i.e., such seal has deficiency because may be possible toalter, open, manipulate a good without leaving evidence of the openingnon clearly.

The patent U.S. Pat. No. 5,782,513 is referred to a mechanical securityseal of ergonomic design having an anchoring capsule, with a pawl systemassociated to a female element and a male element with arrow-shapedguide shoes, such invention presents the inconvenient that thearrow-shaped guide shoes may be replaced by the proximities to the sidewalls, i.e. the design of this system allows pushing the guide shoethrough small perforations to the sides for being violated withoutleaving evidence.

On the other hand, the patent CA206938 is referred to a security sealfor sealing units comprising two rectangular surfaces; the base and thelid joined along one side by a hinge, however, it has a drawback in thecontinuity between the two cavities, besides that the hinge is not aguarantee that the seal can be manipulated, conversely, if the seal isopened, it leaves no evidence that it has been compromised.

Thus, the above documents have been overcome in novelty, inventive stepand industrial application by the present invention, an issue which isshown below in the description of the embodiments. This inventionprovides resistance of limited opening, likewise in the art there is notany security seal that by conductivity between installed terminalsthereof, may indicate that it has been opened, making clear that theproduct was either altered or accessed; therefore, the device of thepresent invention allows to detect and counteract alterations,modifications, theft or pulling out of goods or products it wishes toprotect because it can be of a transparent thermoplastic material whichbecomes apparent its fracture and handling; concisely the seal of thepresent invention increases by far the safety and ability to demonstrateunwanted openings, keeping standards of the ISO/PAS 17712 standard forsecurity seals level 2.

The drawings illustrate the embodiments of the invention and along withthe description serve to explain the principles of the invention.Besides, the reference letters are applied to the components, throughthis disclosure. The descriptive terminology has been adopted in orderto enhance the reader's understanding with respect to the various viewsprovided in the figures, and are not intended to be limiting.

FIG. 1 illustrates an isometric top view of the base (A), in which wecan observe:

-   -   A guide channel (C) through which is passed a cable or wire (T)        (not shown in the figures), usually stainless steel but not        limited to this material, which pass through the base (A).    -   A guide mechanism using a pair of punches (O) serving to        assemble the continuity verification mechanism (N) and a single        arrow-shaped pawl (D) which serves to assemble the cover (H).

FIG. 2 illustrates an isometric bottom view of the base (A), in which wecan observe:

-   -   A pair of punches (O) serving as guide to assemble the        continuity verification mechanism (N).    -   A pair of forming slots(V), in such a way that the base (A) be        injected and removed by injection without problems. These        forming slots (V) are located on the underside of the base (A)        to be in contact with the existing cavity of the base of the        electric meters.

FIG. 3 illustrates a top view of the base (A), in which we can observe:

-   -   Four guide channels (C) so that the cable or wire (T) passes        from one end to another and is divided by a separation or        slot (E) in the central part of such channels (C). This        separation or slot (E) reaches the bottom of the base (A).    -   Two rails (F), where such rails coincide with the separations or        slots (E) of the channels (C).

FIG. 4 illustrates a cutting isometric view of side section of the base(A) to the height of the channel (C), in which we can see:

-   -   The cable or wire (T) emerges from the guide channel (C) on the        other side of the base (A), the cable (T) surrounds, moors or        captures, that wishing to be sealed, and then the cable backs to        the base (A) of the device for traversing it by the other        channel (C) which also presents its separation or slot (E).        Then, the cable is tightened firmly and the lid (H) of the        device is used for closing the seal and maintain the cable (T)        fixed without being able to be released.    -   Then, the verification mechanism is assembled for continuity (N)        which contains the fragile electricity conductor element (U)        (not shown in the figures), for generating the assembly (L).    -   Due to the seal has a unique shape that fits exactly into the        cavity of the meters by pressure, in order to access to the        forming slots (V), it is necessary to cut the cable or wire (T)        that must be secured to the meter and tense after performing the        assembly (L) and therefore it does not allow that the cavity        seal rises.    -   The rail (F) for its part has a tolerance so that the        rectangular punch (I) of the lid (H) matches very tightly.    -   The projection of the isometric angle of the single arrow-shaped        pawl (D) against the horizontal is of 60.33°.

FIG. 5a illustrates an isometric bottom view of the lid (H), in which wecan observe:

-   -   The guide shoe shaped like clamp (J) used to hold the single        arrow-shaped pawl (D) of the base (A), which get in by bending        the material, making very difficult to violate the seal without        causing visible and permanent damage.    -   The lid (H) has a pair of rectangular punches (I) running on the        rails (F) in the base (A). When the lid is assembled (H) with        the base (A). Such punches (I) arrive very near the core of the        base (A) and serves to press the cable (T), one in each guide        channel (C). This generates two curls in the cable (T), one in        each of the channels (C), while captures the curl of the        cable (T) against the core of the base (A), thus, avoiding        displacement or slipping of the cable (T). If found one end of        the cable (T) free or open it indicates that was cut or broken        the violated seal, showing external manipulation.    -   The continuity verification mechanism (N) holds the fragile        electricity conductor element (U) which will be destroyed by the        hook (K) of the lid (H) when trying to remove it eliminating the        electrical conductivity between the terminals (G). The purpose        of this mechanism is to determine whether the seal has been        managed to be opened in non-obvious way when checking the        electrical continuity or no continuity through the tips of a        multimeter in the terminals (G) which are formed to perform the        complete assembly of the seal (L) and thus, verify whether the        seal has been opened

FIG. 5b illustrates a sectional view of the lid (H), in which we canobserve the dimensions thereof:

-   -   The space (b) between the guide shoe shaped like clamps (J) is        2.40 mm.    -   The width (D of the rectangular punches (I) to the base (a) of        the lid (H) is 8.25 mm, while the width (e) of each rectangular        punch (I) is 4.29 mm.    -   The projection of the isometric angle (a) of the guide shoe        shaped like clamps (J) on the base (a) of the lid (H) is 76.29°.    -   The thickness of the base (a) of the lid (H) is 2 mm.

FIG. 6 illustrates a lateral view of the lid (H), in which we canobserve:

-   -   One of the rectangular punch (I) serving as opening barrier        between the guide shoe shaped like clamp (J), resulting more        difficult violating the security seal, because in case of        wanting manipulate it without leaving evidence, should be        achieved open the guide shoes shaped like clamp (J) to release        the single arrow-shaped pawl (D) while the punches (L) limit its        opening and moreover, at the same time should also be avoided        activate the continuity verification mechanism (N) in a way for        not showing that the seal was manipulated, opened or tampered.    -   For avoiding security fails for the forming slots (V) of the        base (A), the top of the guide shoe shaped like clamp (J) is        designed for sealing such slot when making the assembly (L) in a        way that the seal cannot be opened in non-obvious way.        Additionally, any attempt to open the already assembled seal        will provoke that the continuity verification system (N) be        activated, since when lifting the lid (H) the hook will destroy        the fragile electricity conductor element (U) eliminating the        electrical conductivity between the terminals (G) and thus        evidencing the opening attempt.

FIGS. 7 and 8 illustrate an isometric view of the continuityverification mechanism (N), in which we can observe:

-   -   A cannel (M) where the fragile electricity conductor element        conductor of electricity (U) that simultaneously serves as        assembly guide for the punches (O) of the base (A).    -   Two pawls (Q) which will serve to make the assembly with the        base (A).    -   A lug (R) serving as fastening support in order to perform the        assembly with the base (A), where by a click indicates that such        assembly has been carried out correctly.    -   A pair of channels (S) which together with the punches (P) of        the lid (H) will form the cavities (G) which will be used as        terminals for check electrical continuity.

FIG. 9 illustrates an isometric exploded top view of the base (A), thelid (H) and the continuity verification mechanism (N) before theassembly (L), in which we can observe:

-   -   In the closure mechanism, the sealing faces both the base (A) as        the lid (H) are driven by axial forces to fit perfectly, because        of the magnitude of effective pressure between the guide shoe        shaped like clamp (J) of the lid (H) and the single arrow-shaped        pawl (D) of the base (A) in such a way that there is a click        when assembling.    -   Similarly, the sealing faces of the continuity verification        mechanism (N) having the fragile electricity conductor        element (U) are pushed against the base (A) for being assembled,        fitting perfectly after that the pressure magnitude between the        pawls (Q) of the continuity verification mechanism (N) be pushed        by the axial forces generated by effective pressure applied for        carrying out such assembly while the punches (P) of the lid (H)        and the punches (O) of the base (A) serve as guide for the        channels (S) and the channel (M) of the continuity verification        mechanism (N), respectively, when performing the assembly (L)        where by means of a click indicates that such assembly has been        carried out correctly.    -   In the perfect assembly (L), the tension bending plays an        important role according to the material for the movement        transmission since it is directly proportional to the resistance        of such movement.

FIG. 10 illustrates a lateral view of the assembly process (L), in whichwe can observe:

-   -   First of all, the cable or wire (T) must be placed traversing        one of the cavities (C) of the base (A) from end to end. Then,        this cable or wire (T) must be arranged so that it surrounds,        moors or capture that wanting to be sealed. Finally, such cable        or wire (T) must back and traversing from end to end from the        other channel (C) of the base(A).    -   Secondly, the lid (H) must be assembled on the base (A) in the        direction indicated by figure (FIG. 10) while the punches (I) of        the lid (H) are guided by the rails (F) of the base (A) until        the guide shoes shaped like clamp (J) of the lid (H) open by        bending and back to their original shape when ending surrounding        the single arrow-shaped pawl (D) of the base (A).    -   Finally, the continuity verification mechanism (N) is assembled.        For that the fragile electricity conductor element (U) is placed        in the core of the channel (M) of the continuity verification        mechanism (N). Then, such mechanism is fastened (N) by the        lug (R) and pressed against the base (A) previously assembled        with the lid (H) in the direction indicated by the figure        (FIG. 10) while the top face of the continuity verification        mechanism is kept into contact with the bottom face of the lid        (H), the cavities(S) of the continuity verification        mechanism (N) are aligned with the punches (P) of the lid (H)        and the punches (O) of the base (A) are inserted in the        channel (M) of the continuity verification mechanism (N) until        the pawls (Q) of the continuity verification mechanism (N) have        bended and returned to their original shape fastening against        the inner face of the base (A).    -   Finally, and if the user wishes, the lug (R) of the continuity        verification system (N) may be fractured by pressuring it in        some direction perpendicular to its side faces.    -   Thanks to the continuity verification mechanism, being opened in        non-obvious way, the user always can realize that the seal has        been violated by the continuity checking between the cavities or        terminal (G), which are formed in the assembly (L) between the        punches (P) of the lid (H) and the channels (S) of the        continuity verification mechanism (N). Therefore, when there is        not continuity between the terminals (G) it is indicative that        somebody opens or try to open the seal, the enough as to        activate the continuity verification mechanism (N) by breaking        the fragile electricity conductor element (U) contained in the        channel (M) with the hook (K) of the lid (H).    -   The magnitude of the effective pressure of assembly is too        important. The main contacting faces in the assembly process of        the lid (H) and the base (A) are constituted by the guide shoe        shaped like clamp (J) and the wedge formed by the single        arrow-shaped pawl (D), respectively. Similarly, the main        contacting faces in the assembly process of the continuity        verification mechanism (N) and the base (A) are constituted by        the sloped face of the pawls (Q) of the continuity verification        mechanism (N) and the inner wall of the base (A). If this        effective pressure of assembly is very high in any of the cases,        both the wedge formed by the single arrow shaped pawl (D), the        guide shoe shaped like clamp (J), the pawls (Q) of the        continuity verification mechanism (N) and the inner wall of the        base (A) may be fractured. Therefore, when fitting and        assembling the pieces with an excessive effective pressure, the        lid (H), the base (A) and the continuity verification        mechanism (N) can be destroyed.

FIGS. 11 and 12 show the assembly (L) from a top and bottom isometricview, in which we can observe:

-   -   The longitudinal punches (P) of the lid (H) together with the        channels (C) of the base (A), when making the assembly (L),        generate the cavities (B) by which the cable (T) will pass.        Likewise, the longitudinal punches (P) of the lid (H) and the        channels (S) of the continuity verification mechanism (N), when        making the assembly (L), generate the cavities (G) which will be        terminals by which the continuity will be reviewed with a        multimeter.    -   The seal creates a flat surface between the rear of the        electrical meters installed in Mexico and the top of the lid        (H), can be accompanied by a highly destructible RFID tag (not        shown in the figure) and of a single use joining of a single use        joining the top surface of the lid (H) with the rear of the        electrical meter. The breaking of the tag or its absence makes        evident to the naked eye the opening of the seal.    -   The RFID technology allows reviewing remotely by a wireless        reader a single identification number, which, if not correspond        with the user records, makes evident the manipulation or        alteration of the seal. If this tag is intended to be removed        the RFID antenna is destroyed and cannot be read, likewise if it        is replaced by some false tag which does not have the        corresponding RFID antenna or in case of having RFID antenna        which is programmed with a single identification number which        does not correspond with the single identification number in the        records of the user. All this generates evidence of the        violation or violation attempt. In addition, to attempting to        violate the meter, it would be necessary to break the tag or        RFID tag, if this has been added after performing the assembly        (L), and accommodate the seal in the cavity. Such cavity adheres        the upper face of the lid (H) to the meter base avoiding lifting        the seal of the cavity. Therefore, in addition to the lack of        electrical conductivity between terminals (G), the opening        evidence of the seal will be observed in the violation of the        tag or RFID tag and/or finding one end of the cable (T) free,        which will indicate that it was cut.    -   For the above, the system may include one or more intelligent        RFID tags, wherein such tags involve the advantage of presenting        traceability, making possible the automatization of the process        of verification of the seals and meters, in combination with a        software for the remote checking using a handheld RFID terminal        as checking method, wherein such software manages the        information and transmits it to a database for the auditing        control of the integrity of seals and meters.    -   For all the above disclosed, the seal or assembled security        seal (L) get in by pressure in the cavities of the meters,        therefore, in case that the seal be outside of such cavity its        external manipulation is evident.

FIG. 13 illustrates a view of the front cutting section of the assembly(L) at the same height of the single arrow-shape pawl (D) and guide shoe(J), in which we can observe:

-   -   The assembly system (L) of the base (A) and the lid (H), where        the single arrow-shaped pawl (D) is used and the guide shoe        shaped like clamp (J) for making such assembly (L). The use of a        guide shoe shaped like clamp (J) characterize to our seal, since        it avoids the possibility of drilling to press the guide shoe        shaped like clamp (J) and open the seal, since drilling is not        enough, but the guide shoe (J) should be pulled, not push it, in        order to release the assembly, something mechanically very        complicated and more in small sizes.

FIG. 14 illustrates a view of the top cutting section of the assembly(L) at the same height of the continuity verification mechanism (N).

Broadly, this device keeps closed an electrical circuit between twocavities or terminals (G) located in front of the seal by a fragileelectricity conductor element (U) which is inserted into a channel (M)of the continuity verification mechanism (N) one moments before thatsuch mechanism (N) be assembled with the base (a) and the seal isclosed. This continuity or non-continuity can be checked by the tips ofa multimeter in test mode of continuity, therefore any attempt to openthe lid moves the hook (K) of the lid (H) fracturing the fragileelectricity conductor element (U) contained in such mechanism (N),opening the electrical circuit. Thus, every time that the seal bereviewed the seal can read the continuity between the two cavities (G)and always there should be such continuity. If such continuity is notfound, it is indicative that someone opened or tried to open the sealthe enough as to activate the mechanism.

The material used to embody the seal or safety seal for electricitymeters installed in Mexico of this invention, is the ABS thermoplastic,such material allows that the seal be perfectly uniform, ensuring anexcellent contact between the base (A), the lid (H) and the continuityverification mechanism (N), unlike conventional seals.

The property of the ABS thermoplastic (acronym derived from the threemonomers: acrylonitrile, butadiene and styrene) has good mechanicalresistance to the impact, being more resistant than polystyrene due tothe nitrile groups, therefore, such properties compared with the abovematerial are: high tensile strength allowing withstand the effectivepressure without breaking, high tensile strength, high resistance toabrasion and impermeable to water. However, the present invention is notlimited to use ABS thermoplastic material, on the contrary, thisinvention may be embodied with any other material.

The manufacturing method of the guarantee seal object of this inventionwas carried out by plastic injection to reduce costs of mass production,however, such method is not limited to this, but rather can be carriedout by any other manufacturing method. It is apparent to those skilledin the art that various modifications and variations to the structure ofthe present invention without departing from the spirit and scopethereof.
